Description

Technical Field

[0001] The utility model relates to the photovoltaic field, in particular to an automatic feeding device. Background Art

[0002] The common automatic loading device for photovoltaic panel installation robots in the prior art is a device that forks and flips the entire photovoltaic panel and lifts it to a working state. That is to say, after the automatic loading device forks and lifts it from the front, it uses the left and right rotator to rotate the rotating frame together with the entire photovoltaic panel by 90 degrees, so that the photovoltaic panel is placed flat and enters the working state. The above solution has the following problems:

[0003] 1. After the whole photovoltaic panel is lifted and flipped, the rotating frame and the whole photovoltaic panel are suspended in the air. At this time, the automatic loading device is following the installation robot. The weight of the whole photovoltaic panel is large. After the bumpy road surface is transmitted to the suspended rotating frame, the vibration is aggravated, which will cause the photovoltaic panels to collide with each other and be damaged;

[0004] 2. After the whole photovoltaic panel is lifted and flipped over and suspended in the air, the overall center of gravity of the installation robot moves backward, and it is relatively unstable in the direction of tipping backward. When the whole photovoltaic panel is moved on a slope with the installation robot, there is a risk of tipping backward.

[0005] In summary, the automatic loading device commonly used in photovoltaic panel installation robots in the prior art has potential safety hazards during operation. Utility Model Content

[0010] As a further improved technical solution of the utility model, it also includes an elastic member, and the support member is connected to the first frame or the second frame through the elastic member.

[0011] As a further improved technical solution of the utility model, the elastic member is a leaf spring.

[0012] As a further improved technical solution of the utility model, it also includes a connecting plate, and the supporting members are two on the left and right sides, and the two supporting members on the left and right sides are connected to each other through the connecting plate.

[0013] As a further improved technical solution of the utility model, it also includes a rotator, and the second frame and the first frame are connected through the rotator.

[0014] As a further improved technical solution of the utility model, it also includes a controller, the rotator includes a fixed part and a movable part, the fixed part is fixed to the inner wall of the first frame, and the movable part is fixed to the outer wall of the second frame, and the controller controls the rotation of the movable part relative to the fixed part.

[0030] Please refer to Figures 1 to 9 As shown, the utility model discloses an automatic loading device 100, including a lifting mechanism 1, a forklift frame 2 and a support member 3. The forklift frame 2 includes a first frame 21 and a second frame 22, wherein the first frame 21 is connected to the lifting mechanism 1 and has a raised state and a lowered state, and the second frame 22 is connected to the first frame 21, and the second frame 22 can rotate relative to the first frame 21 and has a flat state and a vertical state. The support member 3 is arranged on one of the first frame 21 and the second frame 22 to rise and fall with the first frame 21 or rotate with the second frame 22. Therefore, the support member 3 of the utility model does not contact the ground before entering the working state and can contact the ground in the working state, so that the support member 3 of the utility model can provide support to the forklift frame 2 and the photovoltaic panel 200 supported by the whole support, so that the forklift frame 2 and the photovoltaic panel 200 supported by the whole support in the working state can avoid safety hazards such as vibration, collision, and backward tipping.

[0031] Please refer to Figures 1 to 7 The support member 3 is arranged at the front of the second frame 22 in a horizontal state and can be changed to support the bottom of the second frame 22 in a vertical state as the second frame 22 rotates, so as to provide support for the second frame 22. For details, please refer to Figure 1 and Figure 2 , which shows the first embodiment of the automatic feeding device 100 of the utility model, the support member 3 is arranged at the front part of the second frame 22 in a flat state. Figure 3 , the second frame 22 is in a flat state, and the rear of the first frame 21 and the rear of the second frame 22 are both open, so that it is convenient for the forklift frame 2 to fork the whole photovoltaic panel 200 until the whole photovoltaic panel 200 is on the forklift frame 2; please refer to Figure 4 When the whole photovoltaic panel 200 enters the forklift frame 2, the forklift frame 2 and the whole photovoltaic panel 200 thereon need to be lifted to a certain height in order to facilitate the moving position of the support member 3 during the rotation process; please refer to Figure 5 , which shows a state diagram of the forklift frame 2 and the photovoltaic panel 200 supported thereon during flipping. Because the utility model is flipped at a certain height, it is possible to move the support member 3 from the front of the second frame 22 in a horizontal state to the bottom of the second frame 22 in a vertical state. In other words, the lifting mechanism 1 in the utility model has a certain rationality. If the forklift frame 2 is flipped directly after being picked up, the support member 3 will be rotated 90 degrees from the front of the second frame 22 in a horizontal state to the bottom of the second frame 22 in a vertical state, which is likely to be disturbed by the ground and cannot be rotated.

[0032] In the second embodiment not shown in the figure, the support member 3 is arranged at the bottom of the first frame 21. When the first frame 21 is raised, the support member 3 leaves the ground; when the first frame 21 is dropped, the support member 3 contacts the ground to provide support for the forklift frame 2 as a whole. In this case, the support member 3 is arranged at the bottom of the first frame 21 which is not flipped. It only rises and falls with the first frame 21. When the first frame 21 is dropped, the support member 3 contacts the ground to provide overall support for the force. The structure of the second embodiment is relatively simple, and it is not the focus of the present utility model, so it will not be described in detail.

[0033] The automatic feeding device 100 of the present invention further includes an elastic member 4. The support member 3 is connected to the first frame 21 or the second frame 22 via the elastic member 4. Figure 2 In the first embodiment shown, the support member 3 is connected to the second frame 22 via the elastic member 4. Therefore, the support member 3 and the elastic member 4 can be turned over relative to the first frame 21 along with the second frame 22.

[0034] Please refer to Figure 1 and Figure 2 In a specific implementation, the elastic member 4 is a leaf spring. The leaf spring is composed of a plurality of alloy spring sheets of equal width but unequal length to form an elastic beam of approximately equal strength, which is a well-known technique for ordinary technicians in the industry and will not be described in detail.

[0035] Please refer to Figure 2The automatic loading device 100 of the utility model further includes a connecting plate 5. The supporting members 3 are two on the left and right sides, and the two supporting members 3 on the left and right sides are connected to each other through the connecting plate 5. The two supporting members 3 on the left and right sides can provide balanced supporting forces on the left and right sides of the forklift frame 2.

[0036] It should be noted that the elastic member 4 and the connecting plate 5 are not only applicable to Figures 1 to 7 The embodiment 1 shown can also be applied to the embodiment 2 not shown as described above. That is, the support member 3 in both the embodiment 1 and the embodiment 2 can ensure the automatic loading device 100 of the utility model in the working state through the elastic member 4, so that the unevenness of the ground can be absorbed by the leaf spring, reducing the vibration of the forklift frame 2 and the whole photovoltaic assembly 200. The connecting plate 5 in both the embodiment 1 and the embodiment 2 can reinforce the installation of the support member 3 and prevent the support member 3 from tipping over to the left and right.

[0037] Please refer to Figure 8 and Fig. 9 The automatic feeding device 100 of the present invention further includes a rotator 6 . The second frame 22 is connected to the first frame 21 via the rotator 6 to achieve the flipping of the second frame 22 relative to the first frame 21 .

[0038] The automatic feeding device 100 of the present invention also includes a controller (not shown). Fig. 9 The rotator 6 includes a fixed part 61 and a movable part 62. The fixed part 61 is fixed to the inner wall of the first frame 21, and the movable part 62 is fixed to the outer wall of the second frame 22. The controller controls the rotation of the movable part 62 relative to the fixed part 61.

[0039] It should also be noted that the support member 3 is one of a universal wheel and a fixed wheel. The universal wheel can turn 360 degrees to meet the customer's needs for turning and walking at multiple angles; the fixed wheel can only turn and walk in the set direction and angle. Therefore, please refer to the specific implementation method. Figure 1 The support member 3 in the automatic feeding device 100 of the present invention adopts a universal wheel.

[0040] It should be further pointed out that a trailer frame 7 is also provided in front of the forklift frame 2, and the lifting mechanism 1 is connected to the top of the trailer frame 7. A running wheel 70 is provided at the bottom of the trailer frame 7, and the running wheel 70 is also one of a universal wheel and a fixed wheel. Figure 1 The walking wheel 70 in the automatic feeding device 100 of the present invention is also a universal wheel.

[0041] The working principle of the first embodiment of the utility model is as follows: Figures 3 to 7 , the second frame 22 is in a flat state, and the rear of the first frame 21 and the rear of the second frame 22 are both open, so that it is convenient for the forklift frame 2 to fork the whole photovoltaic panel 200 until the whole photovoltaic panel 200 is located on the forklift frame 2; when the whole photovoltaic panel 200 enters the forklift frame 2, it is also necessary to lift the forklift frame 2 and the whole photovoltaic panel 200 thereon to a certain height, in order to facilitate the moving position of the support 3 during the rotation process; during the flipping of the second frame 22 in the forklift frame 2 and the whole photovoltaic panel 200 thereon, the support 3 starts to move from the front to the bottom; when the second frame 22 of the forklift frame 2 changes from a flat state to a vertical state (note: at this time the whole photovoltaic panel 200 changes from a vertical state to a horizontal state), the support 3 also changes to be located at the bottom of the second frame 22; finally, the second frame 22 and the whole photovoltaic panel 200 thereon are lowered by the lifting mechanism 1 until the support 3 touches the ground.

[0042] The working principle of the second embodiment of the utility model is similar to that of the first embodiment, with the difference that: the support member 3 is always located at the bottom of the first frame 21, and is only lifted and lowered but not flipped. When the second frame 22 of the forklift frame 2 changes from a horizontal state to a vertical state (note: at this time the entire photovoltaic panel 200 changes from a vertical state to a horizontal state), the second frame 22 and the entire photovoltaic panel 200 thereon are lowered through the lifting mechanism 1 until the support member 3 touches the ground.

[0043] In summary, the flat / vertical states of the second frame 22 and the whole supporting photovoltaic panel 200 are opposite: it can be understood that when the second frame 22 is in a flat state, it is convenient to fork the whole supporting photovoltaic panel 200 in a vertical state, and when the second frame 22 changes from a flat state to a vertical state, the whole supporting photovoltaic panel 200 changes from a vertical state to a horizontal state, which is convenient for the robot arm to grab the photovoltaic panels 200 one by one.

[0044] Therefore, the support member 3 of the utility model does not contact the ground before entering the working state and can contact the ground in the working state, so that the support member 3 of the utility model can provide support to the forklift frame 2 and the entire photovoltaic panel 200, so that the forklift frame 2 and the entire photovoltaic panel 200 in the working state can avoid safety hazards such as vibration, collision, and backward tipping.

[0045] The above implementation modes are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on the technical personnel in the relevant technical field. Although the present invention has been described in detail in this specification with reference to the above implementation modes, ordinary technical personnel in the field should understand that the technical personnel in the relevant technical field can still modify or make equivalent substitutions to the present invention, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
